chown and file ownership

[superfly2]

Hello,

I would like to create a file (using a perl script) that has a particular
owner and group (say "myowner" and "mygroup"). The script is owned by
"myowner:mygroup" but the file is currently owned by "base:base". The chown
command doesn't seem to work in my script (it returns 0 for the number of
files changed), even though I have added "base" to the myowner and mygroup
lines in my etc/group file.

Any help would be appreciated.

On most Unix-like OSs only root can use the chown syscall can only be
used to change owner.

Note also the "base" is not a number. (perldoc -f chown)

Any help would be appreciated.

Check out the documentation for the Perl chown function and the
underlying chown syscall on your OS.

Right, I used the number for "base" as found in my etc/group file, not the
string "base".

is owned by "myowner:mygroup" but the file is currently owned by
"base:base".

A wild guess: is the directory configured in such a way that files created
inside of it have "base:base" (this would be a Unix question, not a Perl
issue)?

The chown command doesn't seem to work in my script (it
returns 0 for the number of files changed), even though I have added
"base" to the myowner and mygroup lines in my etc/group file.

On most OSs only root can use chown(), so you would have to run your script
as root which of course has other implications.
